R/flash_verbose_fns.R
flash_verbose_max_chg_L.RdDisplays the maximum (absolute) change over all (posterior expected values for) loadings \(\ell_{ik}\). At each iteration, the loadings vectors \(\ell_{\cdot 1}, \ldots, \ell_{\cdot K}\) are \(L^2\)-normalized.
flash_verbose_max_chg_L(curr, prev, k)The flash_fit object from the current iteration.
The flash_fit object from the previous iteration.
Only used during sequential backfits (that is, calls to
flash_backfit where extrapolate = FALSE). It then
takes the index of the factor/loadings pair currently being optimized.
A character string, suitable for printing progress updates.
This function is an example of a function that may be passed to
parameter fns in function flash_set_verbose to
customize the output that is printed after each greedy or backfitting
iteration. See flash_set_verbose for details and examples.
